PV-Nodes likely to fail low Do not decrease reduction at pv-nodes which are likely to fail low. The idea of this patch can be described as following: during the search, if a node on the principal variation was re-searched in non-pv search and this re-search got a value which was much lower than alpha, then we can assume that this pv-node is likely to fail low again, and we can reduce more aggressively at this node.
